about

Latest versions are now available on GitHub:

https://github.com/bj-rn/texconvgui/releases

Simple GUI for MS Texconv.
Obviously inspired by u7angel's DDS Converter.

Alternatives:

v2.0-beta1

rebuild from scratch using vvvv and the VL.ImGui library.
VL.ImGui curently has problems with display scaling, added some workarounds but still looks not quite correct for settings other than 100%
unfortunately download- and "install"-size got quite a bit fatter
now open source
if you encounter any problems please make an issue on github

v1.3

updated texconv.exe to latest (08/21), fixes file-extensions
fixed BC options, were broken due to collapsed -bc switch

v1.2

added OpenEXR support

v1.1

now can deal with directories/paths that contain spaces
updated texconv.exe to release feb2019

nice !

antokhio 10/09/2017 - 12:34

hmmph doesn't work for me for some reason....
just says done and nothing converted

bjoern 10/09/2017 - 15:21

Ah maybe try a path without spaces. Might have forgotten to quote.

antokhio 10/09/2017 - 17:08

Oui!
Now it works, but i can't view any of BC7_UNORM dds lol
just hangs vvvv hmmm.... also seems other types of compression also don't work

update: nop BC7 worked like charm, just not with filetex pooled
update 2: even more weird now everything works like charm for whatever reason....
seems like first time it did something wrong.

Also is it necessary to put resolution in "Resizing" or it takes source?

bjoern 10/09/2017 - 20:01

If you leave both at 0 it will take the original size. There are tooltips for every option, just hover over the fields with your mouse. I had "frozen" filetextures too when trying bc7. With the player node everything works fine.
Also with bc7 try Min Compress and see if it makes any difference qualitywise, it's a lot faster.

rSyndrome 26/02/2019 - 16:50

Hi there,

Thanks for this useful tool!

As far as I know texConv is the most convenient conversion tool atm to take advantage of the last BC formats, because :

as you say nvtt still has no support of BC6H and BC7 formats
Compressonator is unusable on my machine (Win7 with Windows kit 10 installed), as versions 3.0+ require DX12 and Vulkan, and v2.5/2.6 crash at the end of textures' generation...

Could you share the code of this tool, or add a few improvements to it? The first one I see would be to automatically choose the right number of mipmaps if this number is set (by default) to 0. Indeed the generator fails to convert files if you set a higher number than it's possible to generate, which is quite annoying when you want to convert textures with various resolutions in the same folder.

If by "right amount" you mean all mipmaps you can do this already. Just set Mip Map Level to 0.

Microsoft said

-m number: Number of mipmap levels to generate in the output texture. This setting only applies to DDS output, which defaults to 0 which is generate all mipmaps. Use -m 1 to remove mipmaps.

I chose 1 as default because I use the thing to convert highres videos that are displayed 1:1 – it also decreases encoding time and filesize.

rSyndrome 28/02/2019 - 11:48

Ah, great :) The -m option wasn't explained in detail in the cmd line.

mrboni 04/05/2019 - 10:58

Have people had much luck with BC6 and BC7 formats from this? The BC6 variants crash v4 as soon as the texture is in the render pipeline (filetexture will load it initially, but the crash occurs if you try to render it)

A half HD BC7Unorm image takes around 20s to load.

BC7Typeless crashes texconvgui on conversion

I'm using not the most recent alpha 38.2 x64 with most recent dx11 pack

bjoern 04/05/2019 - 16:16

Sorry, I only use bc7 in conjunction with woei's player which works nicely. FileTexture works for me when set to Load in Background, vvvv won't crash and the texture(s) will load eventually, it takes ages though. As to why you'll have to ask vux. Maybe create an issue at github and provide some example textures for him to debug.

mrboni 04/05/2019 - 17:51

bjoern, thank you - BC6 working great with player!

mrboni 05/05/2019 - 16:07

@bjoern - another question. Does exr work for you? I get the following error - FAILED (88982f50)

bjoern 05/05/2019 - 17:02

Never tried with exr and/or have encountered that particular error.
However it seems to be caused by a missing codec/decoder.

edit:
OpenEXR support isn't enabled by default.

Microsoft said

Support for OpenEXR (EXR) can be added to the texconv utility. Uncomment #define USE_OPENEXR in the source, and add the DirectXTex auxiliary module to the project. See Adding OpenEXR for more details including building the OpenEXR library.

mrboni 05/05/2019 - 20:37

Thanks. I'm using a workaround for now but if I get a chance I'll try that out

bjoern 06/05/2019 - 11:49

@mrboni added exr support. Only tested it with some sample images. Maybe you could try and report back...

mrboni 06/05/2019 - 13:06

Wow thank you Bjoern.

I actually just had to ditch my workaround for various reasons so was about to try to make this work. You saved me loads of time.

It works perfectly, and creates a better pipeline from Resolve / Fusion in to vvvv. I've only tested with 4 channel 128bpp exrs > R16G16F dds. (I had to ditch BC6H as the Player plugin wasn't happy with dynamically changing quantity of visible textures). I don't know how texconv will deal with exrs that have extra channels. If I test I'll let you know

Much appreciated

thedi4bl0 11/08/2019 - 02:14

Hi! thanks for the app, is very fast, but I have a problem xD I don't know that parametres need check for only compress .DDS file to format BC6, I can convert, but bad, is deformed.

bjoern 21/08/2019 - 16:45

Sorry I don't get your question, please rephrase.

Purp_Mete 11/09/2019 - 11:37

Which output format I should use for changing DDS.FORMAT to PNG.FORMAT ?
This tool is awesome

bjoern 14/09/2019 - 11:55

It only converts to dds not vice versa, sorry.

ricaria 01/10/2020 - 10:06

hi, a really usefull tool indeed, but it hardly works for me, i try it at a couple of different computers, i tried it hundreds of times, it worked only a few times. Dont know how and why.

I am trying to convert a sequance of png with alpha to dds . as i said it worked a few times..

i tried using simple folder names and file names like C:\chips and to save the dds file to the same or a different folder again in C:

it just says done and nothing happens. help

aazard 07/10/2020 - 02:26

I love you for open ext support!

tgd 07/10/2020 - 10:26

@ricaria Using it heavily for a project right now with no issues on multiple machines. Just in case: you pay attention to the file mask dropdown menu and whether the filecount field says it found any files to convert?

u7angel 13/10/2020 - 16:07

... and maybe open source it ? or is it already ?

redphoenix 18/06/2021 - 08:18

Hello bjoern! Absolutely lovely tool, using it a lot for Farming Simulator 2019!

One request: Would it be possible to change the file endings to be lowercase instead of uppercase? Some engines do not like uppercase file-endings (like the Giants Engine for Farming Simulator)

bjoern 20/06/2021 - 15:57

redphoenix said

Unfortunately that's the way Texconv writes the files. There is a lower case switch but it affects the whole file name not just the ending and in my opinion that's not really desirable.
See also: https://github.com/microsoft/DirectXTex/issues/170

So for now it would need a second renaming step, idk when I'll have the time to implement that.

bjoern 03/08/2021 - 14:38

@redphoenix: file extensions are now lowercase (version 1.3).

redphoenix 26/09/2021 - 13:01

@bjoern you are an absolute legend!

redphoenix 02/12/2021 - 20:52

Hey bjoern - for some reason with the last update I encounter some instability issue.
Whenever switching away and back to the GUI it closes right away.

bjoern 03/12/2021 - 15:03

@redphoenix you mean switching to another programm, e.g. alt + tab?

lostes 07/01/2022 - 00:27

Hi bjoern. I have no question I just want to thank you for this tool. It really helps (game) artist who are not so technical with creating a lot of content which they otherwise would have give up on out of frustration. Much appreciated!

redphoenix 29/01/2022 - 17:19

@bjoern very sorry for the late answer to this question, but yes (I unfortunately was extremely busy in the meantime)

bjoern 30/01/2022 - 14:46

I've been using it quite often lately and cannot confirm that behaviour.
You could check windows eventviewer for more info on what's causing the crash.

redphoenix 30/01/2022 - 22:20

I will do, thank you.

@redphoenix just guessing but only time it crashed for me was when out of disk space.

bjoern 09/07/2022 - 19:10

@redphoenix sorry for the late reply, re-implemented the tool from scratch. Please try if the errors are fixed in the new version. If you encounter any bugs please create an issue on github instead of posting here.

yar 08/08/2022 - 00:21

VL.ImGui looks very promising

y2keeth 19/05/2023 - 02:32

is RXGB (DXT5)
a option if it is what is it the dropdown menu?

y2keeth 10/06/2023 - 06:25

the up coming texconv.exe will add support for DXT5nm and RXGB DXT5 format variants can these be added to the gui?
